Error message

Hello
After one running the script for 39 minutes, I got this error. What is this error for?

It looks like it is trying to write the checkpoint file, but fails. Could it be that you do not have write permission for the temp-folder?

For better troubleshooting, please provide the script and the full log-file, if possible.

The checkpoint file should have extension .hdf5 (or .nc for older versions of ATK), yours is missing that.
Not sure that 100% is the problem, but at least it's something to check
